memory: omap-gpmc: Fix a couple off by ones

Browse Source 
[ Upstream commit 4c54228ac8 ]

These comparisons should be >= instead of > to prevent reading one
element beyond the end of the gpmc_cs[] array.

Fixes: cdd6928c58 ("ARM: OMAP2+: Add device-tree support for NOR flash")
Fixes: f37e4580c4 ("ARM: OMAP2: Dynamic allocator for GPMC memory space")
